Hi Brandon,
I've never seen this.
Musings:
- Does 'show chassis hardware extensive' also mis-report?
- Have you tried (perhaps not until JTAC have a look at current state
of the device) 'restart chassis-control soft' and/or 'gracefully'?
- I don't know for sure, but I will take an educated guess that
i) this process includes the I2C functions, and that ii) the PEM reports its
serial number via I2C?
- Alternatively you might reseat the PEM, if the chassis configuration
supports this as non-service-affecting?
Hopefully JTAC will bear fruit, or someone else who has actually experienced
this can advise.
Br,
Niall

Subject: [j-nsp] MX480 Show Chassis Hardware irregularities
Hi All,
After replacing a PEM in an MX480 running 14.2R7.5, we noticed that the serial
number for the replaced PEM still shows the old serial when issuing a ‘show
chassis hardware’ and doesn’t reflect the correct serial for the new PEM. I’ve
not gotten anything back from JTAC yet on this, and so far going through other
MX480 and MX960 chassis on different versions of code don’t appear to have this
issue.
Anyone seen this behavior before?
Thanks,
Brandon
